PTB TYPE PIPE CENTRIFUGAL PUMP

PTB TYPE PIPE CENTRIFUGAL PUMP

Overview

ISGB and IRGB detachable piping centrifugal pumps are successful development based upon IS and ISG vertical pumps, embodying the advanced technology abroad and the production expertise of ours and precious experience from the mass users through the years. These detachable vertical centrifugal pumps, provided with original structure and leading technology, are superior to their counterparts. This series of products are recognized ’Qualified’ by National Testing Center for Pump Products, Zhenjiang Branch. As a fill-up of domestic blank, and strictly designed and manufactured to ISO2858, this series of products are provided with the advanced performances in line with the international counterparts.

This series of products are processed with audacious design. Pump shaft is provided with an independent support, a solution to the deficiency of extended shaft supported by motor bearing in ISG and ISW pumps. Impeller and pump body are designed and manufactured with modern outstanding hydraulic model to eliminate the axial and radial force of vertical pumps, making the bearings at pump shaft and motor only encountered with slight axial and radial force. Y series standard motor and detachable structure make it away from the headache of replacing the wearing parts in high-power pumps, such as bearing, mechanical seal, impeller and etc.

Compared with the products of the same kind at home, this series of pumps are distinctively advantaged with steady running, long service life, convenient matching, easy maintenance and etc., making them the ideal substitutes to the conventional ISG vertical pumps, IS centrifugal pumps and S-type double entry pump etc.

Structural Advantages

Rigid connection of pump shaft and motor shaft, little vibration and low noise
With the same diameters for pump inlet and outlet, able to be mounted, like valve, at any a position on pipeline, provided with a base for easy and stable installation of pump.
Pump shaft is provided with independent supporting point to ensure dependable running of motor bearing.
Use of specially structured mechanical seal not restricted by the direction of rotation, dependable running and long performance life;
Distinctive installation structure greatly lessens the floor space of pump, saving construction cost by 30%~50%;
Perfect design to ensure leak-tightness and long service life, saving operation management cost by 40%~70%.
